Application tiled l'uly 20,1906. Serial No 327,037.

To @ZZ whom t may concern:

Be it known that I, THOMAS CARMICHAEL, a citizen of the United- States of America, residing at Carnegie, in the county ot' Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Guard-Rails, of which the following is a s ecification, reference being had therein to t ie accompanying drawings.

This invention relatesto certain new and useful improvements in guard-rails; and the invention has for its object the provision of positive and reliable means in connection with a guard-rail for iirmly holding said rail contiguous to a main rail, whereby said guard-rail cannot become displaced should the flange of a wheel impinge the same or should any abnormal pressure be brought to bear upon the guard-rail.

Another object-of this invention is to provide a guard-rail which will form a seat for its associate main rail, thereby dispensing` with rail-plates where my improved guardrail is used.

My invention resides in a guard-rail having a base-flange extension adapted to lie under a main rail, forming a seat for said rail, while the main rail prevents the guard-rail from being accidentally disglaced.

The detail construction of my improved guard-rail will be presently described, illustrated, and then specificallyl pointed out in the claims.

Referring to the drawings forming part of this specification, like numerals of reference designate corresponding parts throughout both the views, in which- Figure l is a perspective view ot' my improved guard-rail; and Fig. 2 1s an end view of the same, illustrating a main rail in connection therewi th My guard-rail comprises a base 1, a web portion 2, and a head or tread 3. The base l upon its one side is provided with an extension 4, which is approximately one-haltl the thickness of the base l, said base being approximately twice the thickness of an ordinary rail-base, whereby a main rail 5, laced upon the extension 4, will be the same ieight as the guard-rail. This construction provides a shoulder 6 the entire len 'th of the guard-rail, which is parallel relative to the main rail 5 and serves to brace the rail 5 by the base-flange 7 engaging said shoulder. The opposite base-llange S of the rail 5 is braced by a rib or flange 9, carried by the edge of the extension 4, said rib or flange extending almost to the ends of the guard-rail.

The ends ot' the guard-rail are bent or curved outwardly from the main rail 5, and in order that the rib or flange 9 will not interfere with the main rail l remove the rib at the ends of the extension 4, as at. 10, but I maintain the shoulder 6 parallel to the main rail, whereby said shoulder and the rib 9 will lirmly hold the main rail 5.

To secure the guard-rail and main rail to ties or sleepers, I provide thcI base l with spike-openings ll and 12 and the rib or flange 9 with openings 1l, a suitable number of openings being provided to accommodate spikes and insure a positive fastening ol' the guard-rail to ties.

The novel construction of my improved guard-rail provides a main-rail scat which will prevent the rails moving or becoming dis laced with relation to one another.

do not care to confine myself to the length, size, or minor details of construction, as suc-h changes in the construction as are permissible by the appended claims may be resorted to without departing from the spirit and scope ot' the invention.

What l claim, and desire to secure by lietters Patent. is-

l. A guard-rail comprising a base, a web, and a tread, and a lateral extension carried by the base and extending the length ot the latter and being ot' less thickness than said base, 'forming a longitudinal shoulder at one marginal edge ot' said base, and ai upwardlyextending llange at the outer end ol said cxtension, substantially as described.

2. A guardail comprising a base, a web, and a tread, and an exteision projecting laterally from thc base and being ol less thickness than said base whereby a longitudinal shoulder is formed along one marginal edge 4of the base, and a marginal flange at the outer edge of said base, the said llange being notched in its upper edge, as and for the purpose descri'oed.

3'. A guard-rail comprising a base, a web, and a tread, the base having a plurality ol" apertures therethrough, and an extension projecting from one edge ot' said base and being of less thickness than the basc whereby to form a longitudinal shouldci` :1-" ljacent said apertures, the extension. adapted to receive a main rail, and. said openings adapted to rcceive spikes securing both lhe main rail and the guard-rail to cross-tics.

4. A onepiece guard-rail comprising 'a yIn testimeny whereoll I aflx my signtuie base, a Web, arid a treed, end a main-railfrein the presence of two witnesses. ceiv'mg extension projecting laterally from I the base and being of less thickness than the THOMAS CARMICHAEL' 5 Ybase, and a marginal flange en the outer edge Witnesses:

of said extension, substantially as shown and MAX H. SROLOVITZ,
